​Can't open KOD db file /var/lib/sntp/kod for writing: Permission denied This bug is easy to fix. The permissions are not set properly for the file /var/lib/sntp/kod in Debian Buster.
The permissions should be -rw-rw-rw- 1 root root 0 Jun 13 11:00 /var/lib/sntp/kod Until the bug is fixed, you can fix the permissions yourself using chmod. P.S. Mac OS X also includes sntp. Apple has set the permissions of the kod file (called ntp-kod in Mac OS X) to rw for all users. This solution is preferable than setting the suid bit in the sntp command from a security point of view.
